APPARATUS FOR IMPREGNATING LIQUORS IN BOTTLES.

SPECIFICATION forming part of Letters Patent No. 478,652, dated July 12, 1892. Application filed llecember 12, 1889. Serial No. 333,682. (No model.)

To all whom it may concern.-

Be it known that I, EMIL STERN, engineer, a subject of the King of Hungary, residing in the city of Vienna, in the Province of Lower Austria, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in the Process of and Apparatus for Impregnation of Any Liquors Directly in Bottles, Pitchers, or Siphons, of which the following is a specification.

The present invention relates to a process to impregnate any liquors directly in bottles, pitchers, or siphons with carbonic-acid or any other gas, which may be done by any one and at any time easily and without any danger. This process consists, essentially, therein that hulls or cases containing the liquid or compressed carbonic-acid or any other impregnating gas are adjusted upon bottles, pitchers, or siphons filled with any liquor or other beverage,(in or outside of said bottles, dac.,)and eventually may serve, at the same ti1ne,to cork them, and by opening the closed hulls or cases the impregnating-gas contained therein is caused to pass into the filled bottle, pitcher, or siphon in order to impregnate the beverages contained therein.

In the accompanyingdrawings, Figure l is a vertical section elevation. Fig. 2 is a side View of the same. Fig. 3 is a vertical sectional view of a modification.

Fig. l of the accompanying drawings represents a hull or case for this process in vertical section. The gas is introduced, either compressed or liquid, into the upper part a, which, for instance, is represented in the drawings in the form of a ball, of a case or hull, shaped in any manner, by means of a longitudinal canal c, a screw-spindle f, and the outlet-canal e of the hull or case, and it is closed by means of a piston cl, consisting, preferably, of india-rubber. The piston d reposes loosely on a flat disk 6 and on a second disk 6', which is convex at its under part and fixed in a hull f, screwed rigidly on the upper end of the spindle f. The spindle f itself is screwed into the hull or case. The piston d reposing loosely on both movable disks 6 and e in the inner part of the hull f, the upper end of the piston, which reaches from the hull f, is pressed against the outlet of the canal e in the neck I), if the spindle is screwed upward orif the hull or case is screwed downward, without-changingitsposition orbeingturnedtherewith, and in such a manner that in consequence of its elasticity it binds itself rigidly against the outlet of this canal c and closes it completely, whereby the highly-compressed gases in the hull a are entirely out off. A little disk g, fixed loosely in the part a of the hull or case and lying against an inner ringshaped projection a of the latter, and a second disk 2', screwed into the before-mentioned part a of the hull or case, forms with a little disk 77,, of india-rubber or leather, which is arranged between the two former ones, Ia kind of stuff-box for closing the space I I hermetically. The spindle f reaches through the three disks g, h, and 'i and plunges below into the neck-piece 7a of a disk 10. In the length of this neck-piece it it is not cylindrical, as in the other part, but prismatical, in order not to be turned round therein. By screwing rigidly ascrew-nutl (on which eventually a second screw-nut may be screwed) the spindlef is fixed into the neck-piece On this screw-nut I a case or valve 0, of india-rubher, is arranged, (after the hull a has been filled with gas,) which is provided with one or more side openings 0. The said valve 0, of india-rubber, allows the gases to enter into the bottle, pitcher, or siphon, being pressed down by the highly-compressed gas coming from the under end of the spindle in such a manner that the gas may enter into the side openings 0 and through these into the bottle; but in inverse sense it hinders the entering of the air and of the liquors from the bottle, pitcher, or siphon into the hull, laying itself against the under end of the spindle as soon as the current from the gases from the case or hull ceases in consequence of its elasticity, and at the same time by the pressure of the gas in the bottle, and thus closing the canal c.

In the drawings the valve 0 is shown lying against the under end of the spindle f. A screw-nut t, screwed on the outer side of the neck 70', causes, if screwed up or down, the opening or closing of a valve 11/ in the canal u of the disk 70. A disk or ring Z, of indiarubber, arranged below the disk is, closes the hull or case at the neck of the bottle, pitcher, or siphon. The bull or case isfas'tenedto the neck of-thevessel by means of a hollander p, which is screwed on the neck-ring q, provided with a worm of a screw. The said ring may be provided with a handle 3 in order to hold it.

The practical use of the described device is essentially as follows: The bottle, pitcher, or siphon is filled for. about three-fourths of its capacity with any liquor to be impregnated and the bull or case is fixed on the neck of one ofnthe mentionedvessels by means. ofthe hollander 19. If this is done,.the hollander p is held by one hand (preferably by the left hand) and by the other hand the case or hull a is turned round about ninety degrees to the left and immediately back to the right into wt-he original .position. If turned to the left,

the bull or moves upward, so that the-pis- .ton d Withdraws from the canal c,- the latter is openedandthrough it a part of the compressed-gas enters into the space II, from here through the canal c of the spindlef into the valve 0, of-india rubber, and, raising this latter, throughits side openings 0 into the bot- "tle, pitcher, or siphon. A turning to the right,

following rapidly after the turning to the left, of the hull a,'prevents the whole quantity of the gas from entering at-once from the hull into'the bottle. "The quantity streaming out is==justly=sufficient to' raise the atmospheru ica'l air contained inthe liquor and in the empty space-of the vessel, which can. take *place so much the more easily, the air in most cases being specifically lighter than the'compressed gas. Themixing of'the latter with the liquor may be accelerated by shaking *the-bottle, &c. If after this process the screwnutt is screwed a little upward, the valve to is raised-by the inner pressureandthe atmos-' *pherical air and a littlequantity of gas stream out from the bottle, &c., through the opening u,-so that the liquor becomes perfectly free from the atmospherical air, this being a-chief condition for well impregnatin The streaming out of the air takes place very rapidly in consequence ofthe inner pressure, and there- I fore arapid screwing-down of the screw-nut tmust follow inorder to close-the valve. By turning now the hull a, to the left the outlet isopened-again, so that the remaining contents of the hull flow into'the bottle, pitcher, or siphon through the canals c c.

-vessel is again shaken a little and the liquor will-be completely impregnated. Of course the compressed 'or dropping liquid gas may be introduced into the bottle, pitcher, or siphon at once, instead ofin two quantities, as. 60

those of Fig. 1.

Now the.

Fig. 2 is aside view of a modification of 'Fig. 1.' This figure represents the apparatus modification, in which the hull, which can be 1 closed, is adjusted below the hollander and .take place by turningthe bull or case a, but

by turning the spindlef, which in this case is not provided with the canal 0; but it has on its end projecting from the neck of the vessel a handle or'buttonfor managing it more easily. In order to close the canal 0 a ring 0 of india-rubber is'adjusted instead. of v the valve of india-ru'bber. 'The other parts of the construction are essentially identical with The metal hulls are tried for carbonic acid with two hundred and fifty atmospheres. They are used, however, only with about fifty-five to sixty atmospheres.

Equally the bottles to be used are examined with thirty atmospheres, and used only with a maximum of six and one-half atmospheres,

so that the working with the described device is quite without .any danger. According to the described method those liquors can also beimpregnated which till now couldnot be 'invention' thisinconvenience falls out, be-

cause/every one can impregnate'the liquor himself at any time.

I claim- 1. Adevicefor impregnating liquids inbott1es with gas, consisting of a receptacle for tle-neck, a passage controlled by a valve leading fromsaid receptacle to the bottle, said 'valve'being opened and closed by the upward and downward: movement of the receptacle, and a port in an annulus, communicating with the interior of the bottle and controlled by a valve and a ring for. the purpose of allowing-the atmospheric air and superfluous 'gas to escape, substantially as described.

In testimony whereof I sign this specification in presence of two subscribingwitnesses.
